Dibenzothiophene oxidation in a model diesel fuel using CuO/GC catalysts and H2O2 in the presence of acetic acid under acidic condition

Ionothermal Synthesis of Metal Oxide-Based Nanocatalysts and Their Application towards the Oxidative Desulfurization of Dibenzothiophene

“…e chemical treatment of as-prepared metal-containing ILbased complexes was performed as reported by our group earlier [29]. e catalytic reactions were performed using a previously reported method by changing the catalyst [30]. A mixture of n-hexadecane and acetonitrile (50 mL each) was taken in 250 ml round bottom flask.…”

3D-printing of integrated spheres as a superior support of phosphotungstic acid for deep oxidative desulfurization of fuel

“…As shown in Fig. 4 (a), we investigated the effect of reaction temperatures on the desulfurization activity [64] . As shown in the result that the desulfurization performance of the catalyst at different temperatures follows the order of 70 °C > 80 °C > 60 °C > 50 °C in turn.…”

Roles of the structural defects and the combined acidity of H3PW12O40/Zr-MCM-41 catalysts in ultralow sulfur diesel production

“…The total cost of the combined ODS process is estimated to be reduced by approximately 15-20% in comparison with HDS. 5 Our previous investigations showed that for ODS reactions, the catalytic activities of some transition metal oxides, such as WO 3 and MoO 3 supported on mesoporous SBA-15 solids 6,7 or CuO on activated carbon, 8 are largely controlled by the metal oxidation states, surface acidity, and the molar ratio of oxidant to sulfur. In particular, it is found that the oxidative removal of refractory aromatic organosulfur compounds is sensitive to the Lewis (L) acidity of the metal oxide supported catalysts, as evidenced by the fact that the sulfur conversion is almost proportional to the number of surface L acid sites.…”
